  • ELECTROSTATIC LENS STRUCTURE
    Publication number: 20170309438
    Abstract: An electrostatic lens comprising a first conductive plate with a first aperture, a second conductive plate with a second aperture, the second aperture being substantially aligned with the first aperture, a voltage supply for supplying a first voltage to the first conductive plate and a second voltage to the second conductive plate, the first voltage being lower than the second voltage, and an insulating structure for separating the first conductive plate from the second conductive plate. The insulating structure comprises a first portion in contact with the first conductive plate and a second portion in contact with the second conductive plate, the first portion having an overhanging portion and the second portion having an indented portion at an edge of the insulating structure, so that a gap is formed between the overhanging portion and the second conductive plate.
    Type: Application
